Japanese Porcelain: Where It Came From and How It Differs from Ceramics
Japanese porcelain is tableware made from white vitrified clay, which was first produced in Japan in the town of Arita in the early 17th century, much later than in China. The raw material was found on Mount Izumi near Arita, and the porcelain was shipped by sea through the port of Imari — hence the two names for the ware, "Arita-yaki" and "Imari-yaki." What distinguishes it from ceramics is kaolin, a higher firing temperature, and a ringing body.
A reader searching for "Japanese porcelain" almost always confuses it with ceramics — and not without reason: the difference is subtle to the eye, and the cause lies in the raw material and firing temperature. Let's look at where Japanese porcelain came from and why "Arita" and "Imari" are not different productions but the same ware. We'll also see which schools decorated it differently and how it reached Europe before Chinese porcelain returned there.
Arita: Where the Raw Material Was Found and Why the Porcelain Has Two Names
Japanese porcelain began in the town of Arita, in what is now Saga Prefecture, not all at once across the country. The potter Ri Sampei, of Korean origin, came to Hizen after Toyotomi Hideyoshi's campaign in Korea. In 1616 he found porcelain stone on Mount Izumi near Arita and opened the Tengutani kiln — so, according to legend, the first Japanese white porcelain appeared. Modern excavations show that firing may have begun earlier, in the 1610s, in the western part of Arita, and historians today are refining the role of Ri Sampei himself as the sole founder of the craft.
The Port of Imari: Why One Ware Has Two Names
- 1616 — according to legend, the year Ri Sampei found porcelain stone and fired the first white porcelain.
- 1610s — according to excavations, firing in Arita may have begun several years earlier, in the western part of the town.
- The port of Imari — the only route by which porcelain from Arita left by sea for the rest of Japan and for Europe.
- "Arita-yaki" and "Imari-yaki" — the same ware under two names: after the place of manufacture and after the port of shipment, not two different productions.
How Porcelain Differs from Ceramics: Clay, Fire, and Sound
Porcelain is made from kaolin — a white clay with a high content of aluminosilicates. Ceramics are made from coarser clay with impurities of iron and other minerals. Porcelain is fired at a high temperature, around 1300 degrees; ceramics usually lower, around 1200 degrees. This affects the body: in porcelain it vitrifies almost to a glassy state, becomes white, and in a thin layer is translucent; in ceramics it remains porous, opaque, and usually colored under the glaze.
How to Tell by Light and by Sound
| Feature | Porcelain | Ceramics |
|---|---|---|
| Raw material | Kaolin, white porcelain clay | Ordinary clay with impurities |
| Firing temperature | About 1300 °C | About 1200 °C |
| Body | White, vitrified, does not absorb water | Porous, usually colored |
| Against the light | Thin edge is translucent | Not translucent |
| Sound when tapped | Ringing, glassy sound | Dull, short sound |
Kakiemon, Nabeshima, Kutani, and Demand from Europe
Within Hizen porcelain, several schools of decoration emerged. In the Kakiemon workshop, by the end of the 17th century, the nigoshide style was perfected — a milky-white ground with sparse decoration in red, yellow, and green; the secret of this ground was kept by the workshop for generations. Nabeshima was made in a separate kiln maintained by the clan of the same name: this ware was not sold but given as gifts to the shogun and other lords. Kutani-yaki is porcelain from what is now Ishikawa Prefecture, recognizable by its dense, almost solid decoration in several bright colors.
Dutch Demand: How Porcelain Reached Europe
- 1644 — the Ming dynasty fell in China, and the porcelain trade was shaken.
- 1656 — the new Qing dynasty forbade merchant ships to go to sea, and the export of Chinese porcelain almost stopped.
- The Dutch East India Company ordered ware from Hizen craftsmen based on Chinese porcelain models — so from the mid-17th century the export of Japanese porcelain to Europe began.
- When Chinese exports resumed, the Asian market again went to China, but porcelain from Arita and Imari continued to be shipped to Europe for a long time.
磁器: The Character That Shares Its Meaning with Magnet
磁 — значение: magnet, porcelain — онъёми: ジ — 14 штрих(ов). 磁 — "magnet" and "porcelain": the same character forms 磁石 "magnet" and 磁器 "porcelain," and dictionaries do not clearly explain how the second meaning is connected to the first.
焼き物 and the Suffix 焼: Ware Named After a Place
磁器 is composed of 磁 and 器 "vessel, ware" — this 器 is also seen in 楽器 (gakki), "musical instrument," and in 食器 (shokki), "tableware." The broader word 焼き物, "yakimono," literally "fired thing," covers both porcelain and ceramics. The same root 焼 "to fire" is placed as a suffix after the name of a town or kiln — thus 有田焼 "Arita-yaki" and 九谷焼 "Kutani-yaki": the name of the craft rests on the name of the place.
| Japanese | Reading | Translation |
|---|---|---|
| 磁器 | jiki · jiki | Porcelain |
| 陶磁器 | tōjiki · tōjiki | General word for porcelain and ceramics |
| 有田焼 | aritayaki · aritayaki | Porcelain from Arita |
| 伊万里焼 | imariyaki · imariyaki | The same porcelain, but named after the port |
| 窯 | kama · kama | Kiln |
| 焼く | yaku · yaku | To fire |
Write 磁 along the guides — the character for "magnet and porcelain," which appears in both 磁器 and 磁石.
FAQ
- What is Japanese porcelain?
- Japanese porcelain (磁器, jiki) is tableware made from white vitrified clay, kaolin, fired at a high temperature. The craft began in the town of Arita in the first half of the 17th century, when suitable raw material was found there, and from there it spread through the Hizen region.
- How does porcelain differ from ceramics?
- Porcelain is made from kaolin and fired at around 1300 degrees; ceramics from ordinary clay and usually lower, around 1200 degrees. Porcelain has a white, vitrified body, a thin edge that is translucent and rings when struck; ceramics have a porous, opaque body and a duller sound.
- Are Arita and Imari the same thing?
- Essentially yes: both "Arita-yaki" and "Imari-yaki" refer to the same porcelain from the Hizen region, just by different names. "Arita" is the name of the town where it was made, "Imari" the name of the port through which it was shipped by sea. They are not two different productions but two names for one ware.
- How is "porcelain" written in Japanese?
- 磁器 is read じき, jiki: 磁 carries the meanings "magnet" and "porcelain" at once, 器 means "vessel, ware." The general word for all fired ware, both porcelain and ceramics, is 陶磁器, tōjiki. Ware from Arita specifically is labeled 有田焼, "Arita-yaki," after the town where it is made.
- Why did Japanese porcelain appear later than Chinese?
- Because suitable raw material — porcelain stone with a high kaolin content — was found in Japan only in the early 17th century, at Mount Izumi near Arita. Before that, only ceramics were made in the country, while China had mastered porcelain technology many centuries earlier.
- How is Japanese porcelain decorated?
- In different ways, depending on the school. The Kakiemon style applies sparse decoration in red, yellow, and green on a milky-white ground. Nabeshima was decorated with particular care because this ware was given as gifts to the shogun and other lords, not sold. Kutani-yaki is recognized by its dense, almost solid decoration in several bright colors.
